Altcoin — frequently asked questions

Does altcoin include Ethereum?

By the strict definition, yes, since altcoin means any coin that is not Bitcoin, though some people treat Ethereum as its own category.

Are altcoins riskier than Bitcoin?

Often they are, because many are newer, smaller, and less proven, but risk varies widely from one project to another.

This definition is educational and not financial advice. Crypto is volatile and high-risk — always do your own research.
